DRAFT-EQA-LIZER.

To all whom t may concern.'

Be it known that I, JOHN FREITAG, a Acitizen of the United States, residing at N iota, in the county of Hancock and State of Illinois, have invented certain new. and useful Improvements in Draft-Equalizers, of which the following is a specification.

My invention relates to draft equalizers, and has forone of its objects the provislon of a simple and efficient draft equalizer.

A further object is the provision o f a strong, durable and light equalizer particularly for use with various agricultural 1m-` plements.

Other objects will appear hereinafter.

An embodiment of my inventionA is indicated in the accompanying drawing in which the ligure is a top plan view of la draft equalizer embodying my invention.

InV the drawingI have indicated a fragment of a plow beam 1 to show the application of'my draft equalizer or horse evener to an agricultural implement. The device is provided with a draft bar 2 connected to the plow beam 1 by a pin 3. Any desirable connection be provided between the draft bar 3 and the tool to which the deviceis to be attached.

f At the front end of the draft bar 2 is an equalizer bar or lever 4 having a plvotpin 5 therein. vAlso pivoted on the pin 5 1s a link 6 which extends rearwardly of the lever 4 and is provided with a pivot pin 7 at its rear end.' Pivoted on the pivot pin 7 at its angular portion is an angular lever 8, one end 9 of which extends across the lever 4, andl theother end 10 of which is disposed substantially parallel with the lever 4. The end 9 of the lever 8 is connected to a link 11 as at 12, and the other end of the link 11 is connected as at 13 t0 a link 14, and the latter connected at one end with the lever 4 as at 15. The front end of the link 14 is connected to a doubletree 16 as at 17. lThe doubletree 16 is provided with two swingletrees 18. l

The end 10 of the lever 8 is connected to a link 19 as at 20, and the front end of the link 19 connected to the angular part of a lever 21 as at 22. The lever 21 is pivoted to one end of the lever 4 as at 23. The other end of the lever 21 is connected with a link 24 as at 25, and at the front end of link 24v Specification of Letters Patent.
